the with 01' saoiilioing any of the. advantages Be it; known that I, :lIARLJl-i OGDEN Pow, oi" tho invention. a oitizon of the United States, roslciln at Z Millhury in the county of Wood and $toiv of Ohio, him 1- invented a. now and useful Sound- Vlovelntonsifier, of which the ,lolhm'hig a spooifioaiion,

This invent-ion relates to sonnd roproilno- 111g appoint-us, and has for its principal ol joot to provide moans whereby cumpnrozivoly woo-h sound waves may he nm-gnillod, t-lm n vi-ntion mng applicable to sound roprmiuolug moi'lilmis of tho p1i mog1'.-\ph, gx-m ihoahon or g xn'mopholiu type, as well as to dil l'ol'eiit forms of sound transmitting dovhrcs. such, for lllfilln-llti, of mo mphonos, spanking iil'u'm oi and tho like.

A lui-thviobjm ol' tho invvnlii'm is to gnodirectly by a diaphragm or other body iocalving 1n cit-ion from sound waves.

A still fill'hllel object of the invention is to provide a sound wove magnifyin op mrzit-us in which numerous short blasts 0? a old, under pressure may be directed a o'mst the 21-hmoshorio air, the duration am uibonsiia' of the lastbeing under tho control of the roproducing stylus of a phonograph or like mo chine, or under the control of a dinphnigm 01" other body that, is operated by sound win-we.

With those and other objects in view, as will more fully hereinafter 1L a mall, the invention consists m certain novel whores of nonsi'auoiziosi and arrangement, of ports, 'hcrei'm alter lull described, illustra 531 in the ins-mmpanying drawings, and partiouhiriy pointed out in tho appended claims, it being undo! stood that. va iuus changes in the form, proportions, size and minor details of the strucfiurv may ho made without departing from i i I i1 flxo oocompmiying drawings :Fig1u o 1 531m elevation, portly 1n sootion, of a. sou nd reproducing and nmgnifying ol puratios o0nstr'icted in accordance will. i, 1e invention, showin the application 0-? lEllOiSlLHIU to a, c lindz'imi record sound ieflroducing moo-him.

In Fig. l is shown a purl ion of a. record a:

of ll sound roproducing maohiuo, and :1 mrtion of IlSflll'lKll)lJX(f-1LII'li1;I( ,tho sound )0): and all of its mm being: eliminated. To the sound hox carriage is Sfl'lli'i'll a disk I 0, which SOIVLH to suopui't :istylu; 11 which may he of tho usual construct-ion and mounted in tho noun! manner. Ono end of the stylus hour.- on the. record, and tho othol' end is com llfifile-zl h a link 12 to the apparatus for non trolling tho flow of tho fluid undo-i" frrossnro, said link oxtondin through In suit able opening 13 foamed in the (llsk. Soom'od to (l 1o disk is if oy'lindriml ir-oriing 1-1 which is prodded at one and with 11. short tub 1 5 for the rocopl iuu of a. mmipot 16 or othoi' device by which tho sound \vm'osm'e ho ho oiu'iiod oil and at, one sido of tho casing is a nipple 16' which may be oonnvot-e-d by a flexible tube 1'? to a suitable 'soun'o of supply ofair, as, or other fluid under phenom-o, this iiuic onloriug the casing through tho in'pyie 16, and pasoing outward through the oonnootion 1 311g m-rorneil by the sound record.

TAU interior of the. casing is rovidod with an minulox'ahmihlor 19 on which is sup orteil a valve seat 38, the latter being in tho orm of a disk that is provided with a lorge number of, radial openings 21 that may be of any de- Sll'Hl slm e, the proferred form being that illustrate in Fig. (Loud extending from tho 5 and this flow boperiphery of this disk is a lever 22 that re- Jects through a slot formed in the peri? cry of the casing in order to ermit eir'cum erential ad ustment of said isk. At the center of the disk is an elon ated hub 25having a threaded opening fort erece tion of a hearing screw 26 having at one an a conical opening for the reception of a 0011627 projecting fromone side of a valve disk 28, the letter being provided with radially extending arms of a she e similar to that of the openings 21 in the isk 20, and so arra ed that in one position of the valve all of t e opening-s21 will be entirely closed. Pro'ect' from the op osite side of the valve die 28 is-a spindle 30 avihg areduced'end portion 31, and provided' with a shoulder 32 against which bears the inner end of a manually adjustable screw 33 that is adapted to a threaded opening zo formed in the end of the cylindrical casing 14, this screw and the screw 26 formin bearings which may be very accurately a justed for the purpose of bnniingthc two valve disks very closely toget er, without, how- 25 ever, bringing them into such frictional contact as might interfere with free movement of the disk-28. To the outer end of the re-- duced portion of" the spindle 31 is secured a rocker arm 35 to which the link 12 ie con- 3 O nected. Theroeker arm is held in plhce by a set screw 36 which permits of circumferential adjustment of the rocker'arms to suit the position of the apparatus. Projecting from the valve s indle 30 is a springarm 38 which is '35 engage by a cam 39 carried at the inner end of a small shaft or arbor 40 which may be adjusted circumferentially in order to varythestress exerted by the cam onthe spring. The shaft is held in any position to which it may 40 be adjusted by means of a small locking screw'42. 'Tl'lIS- cam oficrs slight resistance to'the movement of the valve 28 and keepsthe re reducer stylus in intimate contact with t e record. v In-operatidn, the reproducer stylus will he vibrated as it comes IIItOOOIltMt .with the.

record, and this movement will be transmitted'throu'gh the link 12 and rocker arm 35 to the valve spindle and valve 28,,the latter being moved a distance proportioned'to the depth of the.groove in the record. The all tinder pressure, sup lied to the: casing 14 through the connection 16 will then escape through the openings 21 in the valve disk' 20,

the quantity of mr escapmg and the duration or variation of flow iiemg Foverned b the movementof the disk 28. .he release fluid being under pressure, will impinge against the air under atmospheric pressure in that Go portion of the casin which is oonnectedto the trumpet, and wi set such air into vibration, producing sound waves which correspend in time and duration with those from stem b tached to a perforated disk 50 that is secured to a casing 51 in which is arranged a diaphragm 52- connected' by a link 12 to the valved rocker arm. The casing 51 is proyided with a mouth piece 52, and by speakmg, singin or otherwise producing sound Waves at tlie mouth piece, the diaphragm is set into vibration, and these movements are transmitted to the valve, the latter cmitrolwv lin the release of the fluid under" pressure an roducingsound waves of increased intsnsit in the trumpet or other device emplayer ior conserving or reflecting the sound waves.

1. The combi'nationwith the stylus of a sound reproducing machine, of a casing having an'inlet and an outlet for a fluid under pressure, a stationary valve disk arranged within the casing and provided with radially arranged Passages, a movable valve disk having radia ly disposed arms for closing said pas sages, a stem carrying the movable disk meansfor connecting the stem to the stylus, and means for resisting movement of the said stylus. 1

-2. T18 combination with the stylus of a sound reproducing machine, of a casing having an inlet and an-outlet, of a fluid under pressure, a ported stationary valve disk with m the casing, amovable valve disk, a stem carrying the same, a. pair-of ad'ustable bearings for said stem, an'adjustab e rocker arm carried by the stem, means for connecting the rocker arm to the stylus, a spri arm extending from the stem, and an a justahle cam bearing againstrsaid s ring arm.

3. The com inatiop wit sound reproducingmachineof a casing having an inlet,and an outleti ed valve d sk seated within the casing and Erovidejd with an internally threaded hub, a

sari screw mounted in said .hub, a movable va ve disk, a stem carrying the same and having at one and' aoonieai bee in seated in the screw, the opposite end oi sai screw be-l .in'g reduced in dlameterfto form a shoulder a second screw resting against t e the stylus of a or a fluid under a pressure, 'a circumferentially adjustable port shou1der,'a roki m ad jusbably secured to the geduodend of the stem, 8; link cbnngcting the rocker arm to the stylus, a spring arm Erojeotingfrom thla stem, a cam arranged to 5 ear hzgainsb said arm, an adjustable arbor, or s carrying said cam, and a; set screw for iockmg'said arbor or shaft in adjusted position.
